Science Questions

The primary goal of the DCOTSS mission is to understand how dynamical and chemical processes interact to determine the composition of the extratropical stratosphere, and how that composition may change in response to ongoing changes in the climate system. The phenomena involved, which range from turbulence and deep convection to the continental- and planetary-scale circulations, require observing systems and models that cover a similarly wide range of space and time scales. DCOTSS will employ a novel combination of airborne in situ, ground and satellite-based remote sensing, meteorological analyses, and dynamical and chemical models to address the specific scientific questions discussed below.
